# Third step in NEF-workflow.

#
# Details of this script:
# 
# 1. Runs dcraw in chosen default mode for finished jpg-pictures.
# 2. Extracts exif-tags from nef-files and write them to preview-jpg-pictures.
# 3. Deletes *pre.jpg files from step 1 of workflow.
# 4. Remove Orientation-exif-tag as dcraw has already rotated the picture.
#
# Usage:
# $ runnef      # will process all nef-files in current directory
# $ runnef neffile1.nef neffile2.nef # processes chosen files.
